I have a collection of 70 stories (each story is 1 A4 page) and 35 were written by people with aspergers and the other 35 were written by those without it.

I wanted to compile these 70 stories as a book. I wondered how I would differentiate to the reader, which story was written by those with the aspergers ? Is there any other way than just labelling at the end of a story that 'this story was written by a person with aspergers'?

I know some times authors use asterisks, etc, but not sure how that works. I wondered if you had any advice on this?
